Never heard of a TT doing this before, but one of the claws of my TT were roughing up and digging the serving. Been threatening to rework it for a long time now, and finally got to it. There is a little warning seal that says your warranty is void if it is broken, so if you have the patience, it's best to let TT do it. Having zero patience, I pulled it apart. First thing that struck me was, if you remove the sear pin, this trigger is the same as the Excalibur trigger box. The only major differences that were noticeable were the sear pin and the milled-out spots on the inside of the case halves that keep the sear pin from falling away and jamming the inside of the trigger box. Funny how a lot of the Excalibur shooters had a coronary when Derrick Middleton reworked the trigger box to add an auto-engaging safety and roller sear, but now that Trigger Tech did it, all I hear is crickets..... The claws looked good to the unaided eye, but under magnification, there was a lot of surface pitting, and the edges of those pits were sharp. Took the claw out and re-worked it with emery cloth until the pits in the critical areas were gone, and then spent about an hour with the Dremel to polish everything. Lots of surface pitting on this part, never saw one this pitted, but I only smoothed the areas that had contact with the string; the other areas don't matter. If anyone is interested, the claw spring seems much stiffer than the Excal spring. Its free-standing height is .670 and its diameter is .212. The wire diameter is .024, and the coil spacing is .075. The sear pin itself is .540 long and .098 diameter. As always, when working on triggers, watch out for flying springs and detent balls!
